maxon launches the next generation of positioning controllers - the EPOS4. A high performance module with detachable pin headers and two different power ratings. With a connector board, the modules can be combined into a ready-to-install compact solution. Suitable for efficient and dynamic control of brushed and brushless DC motors with Hall sensors and encoders up to 750 W continuous power and 1500 W peak power. The modular concept also provides for a wide variety of expansion options with Ethernet-based interfaces, such as EtherCAT or absolute rotary encoders.
